hoca can rows be added according to the number of rows returned by the query?

    If Not rstSelect Is Nothing Then
        If Not rstSelect.BOF And Not rstSelect.EOF Then
            Do While Not rstSelect.EOF
                 strSerialNumber = rstSelect![serial_number]
                grdSerialNumber.TextMatrix(totalRecs, 0) = strSerialNumber
                rstSelect.MoveNext
                totalRecs = totalRecs + 1
            Loop
        End If
    End If

I am getting an error for this line

grdSerialNumber.TextMatrix(totalRecs, 0) = strSerialNumber

becasue I set up the grid row property to 2 and I am getting more than that in return.

This might help.

    Do Until rs.EOF
        r = r + 1
        frmMain.flxResults.Rows = r + 1
        For c = 0 To rs.Fields.count - 1
            frmMain.flxResults.TextMatrix(r, c) = rs.Fields(c).Value
            ' See if we need to enlarge the column.
            new_wid = TextWidth(rs.Fields(c).Value)
            If col_wid(c) < new_wid Then col_wid(c) = new_wid
        Next c
        rs.MoveNext
    Loop

i changed it to this:

    If Not rstSelect Is Nothing Then
        If rstSelect.BOF And Not rstSelect.EOF Then
            Do While Not rstSelect.EOF
                r = r + 1
                grdSerialNumber.Rows = r + 1
                For c = 0 To rstSelect.Count - 1
                grdSerialNumber.TextMatrix(totalRecs, 0) = rstSelect![serial_number]
                Next c
                rstSelect.MoveNext
                totalRecs = totalRecs + 1
            Loop
        End If
    End If

but i get the error:

method or data member not found  ( rstSelect.Count )

i am on vb 6.0

thank you.


    If Not rstSelect Is Nothing Then
        If Not rstSelect.BOF And Not rstSelect.EOF Then
            Do While Not rstSelect.EOF
                r = r + 1
                grdSerialNumber.Rows = r + 1
                For c = 0 To rstSelect.RecordCount - 1
                    strSerialNumber = rstSelect![serial_number]
                    grdSerialNumber.TextMatrix(totalRecs, 0) = strSerialNumber
                Next c
                rstSelect.MoveNext
                totalRecs = totalRecs + 1
            Loop
        End If
    End If

Sorry, I just checked back in this morning. I'm glad you got it figured out.

You may not need to test for BOF unless the recordset is used in some other part of your source before you get to your loop. I think EOF would sufice, other than that it looks fine.

            Do While Not rstSelect.EOF
                r = r + 1
                grdSerialNumber.Rows = r + 1
                For c = 0 To rstSelect.RecordCount - 1
                    strSerialNumber = rstSelect![serial_number]
                    grdSerialNumber.TextMatrix(totalRecs, 0) = strSerialNumber
                Next c
                rstSelect.MoveNext
                totalRecs = totalRecs + 1
            Loop
